NGC 7771 galaxy group with IFN (James E.)

NGC 7771 galaxy group with IFN

The NGC 7771 galaxy group also includes NGC 7770, NGC 7771A and NGC 7769 located about 200 million light years away in Pegasus. NGC 7771 is about 75,000 light years across. The bluish edge-on galaxy just below NGC 7771 is PGC 214993 and known as NGC 7771A. The small edge-on (unrelated) spiral to the right of the group is MGC+03-60-031. Galaxies in this group are interacting, making repeated close passages that will ultimately result in mergers. NGC 7771 shows a tidal feature strongly inclined to its disk and aligned with the compact companion NGC 7770 which may be stars stripped from the smaller galaxy (see also “The NGC 7771 + NGC 7770 Minor Merger: Harassing The Little One?” by Alonso-Herrero, et al, 15 Jan 2021). Extensive clouds of foreground dust lie a few hundred light years above the galactic plane and make a clear view of the galaxy group a bit more difficult. (APOD: 21 Jan 2010)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
